Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
A brief description will be given of the water vapor sensor 2:
the water vapor sensor 2, also called a moisture sensor, is able to sense the water vapor content of the gas and convert it into a usable output signal.
The humidity sensor is the simplest moisture humidity sensor and is mainly divided into two major types, namely a resistance type humidity sensor and a capacitance type humidity sensor.
The resistance type humidity sensitive element is characterized in that a film made of a humidity sensing material is covered on a substrate, and if water vapor in air is adsorbed on the humidity sensing film, the resistivity and the resistance value of the element are correspondingly changed, and the moisture can be measured by fully utilizing the characteristic. The method has the advantages of higher sensitivity and poor interchangeability and linearity of products.
Capacitive humidity sensors are typically made of polymeric thin film capacitors. When the environmental moisture changes, the dielectric constant of the humidity sensitive capacitor changes, the capacitance of the humidity sensitive capacitor also changes correspondingly, and the capacitance change amount of the humidity sensitive capacitor is proportional to the relative moisture. The advantages are high sensitivity, good product interchangeability, quick response speed, small moisture lag, easy manufacture, easy realization of miniaturization and integration, and lower measurement accuracy than that of a common resistance type humidity sensitive element.
The burn-out prevention protection apparatus and the burn-out prevention control method of the present invention are described below with reference to fig. 1 to 6.
In a first aspect, the prior art proposes 3 solutions to the realistic problem of unattended easy occurrence of dry pan, scorched pan etc. during cooking. According to the first solution, according to the physical phenomenon that the temperature of water is lower than the boiling point before boiling, the temperature of water is stable at the boiling point after boiling, and the temperature of a container is higher than the boiling point of water after boiling, the dry burning prevention gas stove is designed, and whether the pot is dry burned or not is judged by monitoring the temperature of the pot. The use effect of the scheme is not ideal due to the influence of factors such as cost, fire, steam and the like. The second solution is to provide a timing valve of a front-mounted gas stove, and achieve timing flameout and dry burning prevention through forced timing. This solution is not monitored for dry burn when left unattended. The third solution uses electromagnetic wave signals to illuminate the water surface, determining the boiling or drying of the water according to the state of the reflected wave, but is not usable with some pots covered by metal lids because the electromagnetic waves cannot penetrate the metal.
In view of this, the present invention provides a burn-out protection apparatus, as shown in fig. 1, comprising: an infrared sensor 1, a water vapor sensor 2, a central processing unit 3 and an audible and visual alarm 4;
the infrared sensor 1, the steam sensor 2 and the audible and visual alarm 4 are connected with the central processing unit 3 through a bus 10;
wherein the infrared sensor 1 is used for monitoring whether a user is in front of the stove;
the steam sensor 2 is used for monitoring the steam content above the cooker; the cooker is arranged on a stove plate of the stove;
the central processing unit 3 is used for controlling the water vapor sensor 2 to be started when the stove is started and the infrared sensor 1 detects that a user is not in front of the stove; the water heating alarm is also used for feeding back water heating information to the audible and visual alarm 4 when the water vapor content monitored by the water vapor sensor 2 meets a first condition and controlling the stove to turn off;
the audible and visual alarm 4 is used for giving out a water boiling-up alarm after receiving the water boiling-up information.
Specifically, the above definition implies the following information:
the infrared sensor 1 and the water vapor sensor 2 are arranged above the stove;
the CPU 3 is used for knowing the fire-on and fire-off state of the stove by receiving the stove fire-on information transmitted by the fire-on and fire-off control device 13 of the stove;
the infrared sensor 1 feeds back the monitoring result of whether the user is in front of the stove to the central processing unit 3 in real time, and the water vapor sensor 2 feeds back the monitored water vapor content to the central processing unit 3 in real time.
It should be noted that if the stove is on and the infrared sensor 1 senses that a person is in front of the stove, it is explained that the person is cooking, and at this time, the water vapor sensor 2 does not need to be turned on, that is, protection by using the anti-dry protection device is not needed.
After the water vapor sensor 2 is turned on, if the central processing unit 3 acquires information that a user returns to the front of the stove or the stove is turned off, the water vapor sensor 2 is controlled to be turned off.
The invention provides a burn-out prevention protection device which comprises an infrared sensor 1, a water vapor sensor 2, a central processing unit 3 and an audible and visual alarm 4; the infrared sensor 1, the steam sensor 2 and the audible and visual alarm 4 are connected with the central processing unit 3 through a bus 10; wherein the infrared sensor 1 is used for monitoring whether a user is in front of the stove; the steam sensor 2 is used for monitoring the steam content above the cooker; the central processing unit 3 is used for controlling the water vapor sensor 2 to be started when the stove is started and the infrared sensor 1 detects that a user is not in front of the stove; the water heating alarm is also used for feeding back water heating information to the audible and visual alarm 4 when the water vapor content monitored by the water vapor sensor 2 meets a first condition and controlling the stove to turn off; the audible and visual alarm 4 is used for giving out a water boiling-up alarm after receiving the water boiling-up information. The method and the device identify the state of water in the cooker by monitoring the water vapor content above the cooker; when the water in the cookware is identified to be in a dry burning state, the early warning is timely given to a user, and meanwhile, the cooking range is controlled to be closed, so that the dry cooking is avoided, the damage to the cooking range and the cookware is reduced, and the risk of fire occurrence is reduced.
On the basis of the above embodiments, as an alternative embodiment, the first condition is that the water vapor content becomes smaller than the previous time.
It is important for the anti-dry protection device to correctly identify the state of the water in the cooking pot. Fig. 2 provides a schematic diagram of the change of the water vapor content, as shown in fig. 2, in the cooking process of boiling water, soup, porridge and the like, water vapor is generated in the pot, the water in the pot gradually boils along with the extension of the heating time, and the water vapor content above the pot is larger and larger until the water boils, and at the moment, the water vapor content reaches the maximum value. Heating is continued after the water boils, and the water vapor content can be kept at a maximum value for a period of time until the water in the pot is quickly burned out, and the water vapor content is quickly reduced. Therefore, the change trend of the water vapor content can reflect whether the water in the pot is in a boiling/drying state or not.
Namely, when the water vapor flow monitored by the water vapor sensor 2 above the cooking range starts to be reduced, the water amount in the pot is little, and the pot is about to burn off; based on the method, accurate water boiling identification can be realized, and the identification process is simple and convenient to operate.

the audible and visual alarm 4 is also used for giving out water boiling alarm after receiving the water boiling information.
When cooking is performed, if the soup is not found in time after boiling, energy waste can be caused, and gas leakage can be caused by the fact that the fire of the gas stove is extinguished by splashed soup. Therefore, the invention endows the dry-burning prevention protection device with the ability of identifying and reminding users of boiling water, and reduces the risk of fire occurrence while reducing the endless loss of resources.
On the basis of the above embodiments, as an alternative embodiment, the second condition is that the duration of the no change in the water vapor content exceeds a first preset duration.
When the water vapor flow rate monitored by the water vapor sensor 2 above the stove reaches a maximum and continues for a period of time, it is indicated that the water has boiled; based on the method, accurate water boiling identification can be realized, and the identification process is simple and convenient to operate.
In a word, the invention judges the residual quantity of water in the pot by monitoring the water vapor content, and then accurately identifies the boiling and the dry burning of the water.
On the basis of the above embodiments, as an optional embodiment, the central processing unit 3 is further configured to control the stove to turn off under a condition that no instruction for continuing cooking is received from the user within a second preset period of time after the audible and visual annunciator 4 issues the water boiling alarm.
For safety, when a continuous cooking instruction of a user is not received within a second preset time period after the water boiling alarm is sent, the default cooking program is water heating, and the central processing unit 3 sends fire-closing information to the fire-opening control device 13 of the stove so as to enable the fire-opening control device 13 to be turned off.
On the basis of the above embodiments, as an alternative embodiment, the central processing unit 3 is further configured to transmit the water boiling information/water drying information to the user mobile terminal 12 through a WIFI network.
Fig. 3 is a second schematic diagram of a structure of the anti-dry protection device, as shown in fig. 3, the central processing unit 3 may send an alarm message to the router 11, and the router 11 transmits the alarm message to the user mobile terminal 12 through the WIFI network to remind the user of the state of water in the pot being cooked.
In addition to audible and visual alarm, the invention pushes alarm information to the user mobile terminal 12 so as to enrich the source of the alarm information of the user and further improve the use safety of the cooking range.
On the basis of the above embodiments, as an alternative embodiment, the central processing unit 3 is connected with the fire switching control device 13 of the stove through bluetooth;
the central processing unit 3 controls the stove to turn off fire by sending a fire-off instruction to a fire-on/off control device 13 of the stove.
The fire switching control device 13 of the stove is an intelligent control mechanism of the stove, and the invention sets the central processing unit 3 to establish Bluetooth communication connection with the fire switching control device 13 of the stove, thereby facilitating fire switching operation of the central processing unit 3 under the conditions of boiling water and drying water and ensuring safe use of cookware and stoves in the cooking process.
On the basis of the above embodiments, as an optional embodiment, the first preset duration is 30 seconds;
the alarm of the audible and visual alarm 4 is in the form of a flashing alarm and/or an audible alarm.
The first preset time length is a preferred value, and can be adjusted according to the needs in practical application.
